“We’re moving people from needing to choosing to loving Windows, and these devices promise to fuel even more enthusiasm and opportunity for the entire Windows ecosystem,” Chief Executive Satya Nadella said at the event.

Microsoft also said its new tablet and smartphones will come with Windows Hello, an automatic biometric sign-in option introduced earlier this year.

The feature allows users to scan their face, iris or fingerprints to verify their identity and give them access to Windows phones, laptops and personal computers.

Microsoft also introduced a Surface Pen, which has year-long battery life, 1,024 pressure points and comes in five colors with inter-changeable pen tips.

The 950 and 950XL handsets feature a 20-megapixel rear camera, have up to 32GB of storage, 4K video and use liquid cooling technology. Microsoft said storage on the phones could be extended to up to 2 terabytes using a memory card.
